Barium fluoride is an inorganic compound with the formula Ba F 2. It is a colorless solid that occurs in nature as the rare mineral frankdicksonite. [9] . Under standard conditions it adopts the fluorite structure and at high pressure the PbCl2 structure. [10] . Like CaF2, it is resilient to and insoluble in water.

Jun 3, 2024 · The pH value of barium fluoride (BaF2) in water is approximately 7, making it a neutral solution. Barium fluoride is a colorless solid that is insoluble and resistant to water, but it can be corroded by moisture above 500°C and degraded by prolonged exposure to moisture, affecting its transmission in the vacuum UV range.

APPLICATIONS: Barium Fluoride is used in spectroscopic components. It is often suitable for applications in the passive IR band (8 to 14μm) and is often used as a view-port window for thermography. For an equivalent thickness the transmission extends approximately 1μm further into the IR than CaF2.

Jan 27, 2025 · Barium fluoride (BaF2), also known as barium(II) fluoride, is a solid which can also be a transparent crystal. Its molecular weight is 175.34 g/mol. It occurs in nature as the mineral “Frankdicksonite”.

Jun 13, 2014 · BaF2 is a low refractive index (1.40 @ 10 microns) material with low solubility in water. Since it has a good refractive index match to water, in liquid cell applications sampling aqueous solutions it shows minimal interference fringing. As result it has become the preferred window material for infrared biological samples.

Molecular Formula: BaF2 Molecular Weight: 175.32 g/mol Section 10- STABILITY AND REACTIVITY Reactive Hazard: The product is stable and non-reactive under normal conditions of use, storage and transport. Stability: Stable under normal conditions. Conditions to Avoid: Contact with incompatible products. Incompatible Materials: None Known

Apr 19, 2017 · Just a brief explanation. BaF 2 dissociates into Ba 2+ (aq) and 2F- (aq). If you consider F - (aq), it's the conjugate base of the weak acid, hydrofluoric acid (HF). Keeping LeChatlier's Principle in mind, the concentration of the dissolved fluoride ion affects the dissolution of: HF (aq) --> H + (aq) + F - (aq) Still looking for help?
